The Irix Blackstone lens is a wide-angle prime lens designed for cameras with a Nikon F mount. Its optical design includes two aspherical elements, three high refractive index elements and two extra-low dispersion elements to reduce spherical and chromatic aberrations, color fringing and distortion. The Neutrino coating reduces reflections and ghosting, enhancing contrast and color fidelity.
Manual focus features a locking mechanism that secures the focus position, while a distinct click indicates the infinity position. The depth-of-field scale supports hyperfocal and preset focusing techniques. The aluminum-magnesium alloy body has seals to protect against dust and moisture, as well as engraved focus distance and depth-of-field scales with UV fluorescent paint.
